Abstract

An arrangement which is intended for cassette apparatus (2), especially of the video cassette type, which is designed to receive a cassette in a space (3) located in the apparatus (2) concerned, for recording and/or playing back information onto or from a tape contained in the cassette, or a similar information store. The arrangement makes it possible to prevent cassette apparatus from being used at undesirable time and/or by persons who are not authorised to use it. The arrangement is formed by a shaped part (1), preferably similar to a cassette, having a shape which is adapted to fit in the said cassette accommodating space (3), and being designed so that it can be inserted in and accommodated in the said space (3), and can be locked in the said space (30, thereby preventing its unauthorised removal from the apparatus (2), in order to obtain controlled use of the apparatus (2).

Description

DUMMY-CASSETTEWITHLOCKDEVICE

The present invention relates to an arrangement which is intended for cassette apparatus, especially of the video cassette type, which is designed to receive a cassette in a space located in the apparatus concerned, for recording 5 and/or playin back information onto or from a tape con¬ tained in the cassette, or a similar information store.

The main object of the present invention is primarily to provide an arrangement which makes it possible to prevent cassette apparatus of the above-described kind from being 0 used by persons who are not authorised to use it, for ex¬ ample, small children whom it is desired to prevent from watching too much video and/or programmes which are not suit¬ able for them.

The said object is achieved with an arrangement accord- 5 lⁿS o the present invention, which is substantially charac¬ terised in that a shaped part, preferably similar to a cass¬ ette, having a shape which is adapted to fit in the said cassette accommodating space, is designed so that it can be inserted in and accommodated in the said space, and can be 0 locked in the said space, thereby preventing its unauthorised removal from the apparatus, in order to obtain controlled use of the apparatus.

The invention is described in the following by means of an embodiment example, with reference to the accompanying 5 drawings, on which:

Figure 1 shows the arrangement in perspective in a partially cut-away state, viewed at an angle from the front, with the arrangement held in an unlocked state,

.Figure 2 shows the arrangement held in a locked state, 0 Figure 3 shows a schematic cross-section of a cassette - apparatus with an arrangement constructed according to the invention accommodated in its cassette accommodating space, and Figure shows the_.arrangement introduced into the space shown in Figure 3_» in a locked state.

A shaped part, which is designated with the numeral on the drawings, expediently has the shape of a_.cassette which is used in video apparatus 2, for example, or cassette^' apparatus of some other suitable type with a space 3 which is designed to accommodate a cassette which contains a tape or a similar information store which is adapted for record¬ ing and/or playing back information onto and from the^" tape respectively. The said preferably cassette-shaped part 1 is appropriately provided with a cover 4- in the vicinity of the front edge 1A of the part, i.e. the section of the part 1 which is designed to be inserted first through the preferably slit-shaped cassette accommodating space 3 in the apparatus 2, or if the cassette is introduced into the said space downwards from above, the section which is designed to be positioned with the said edge 1A facing inwards into the^' rear part of the apparatus.

At the rear edge 1B of the shaped part, i.e. the section of the part 1 which is designed to be gripped when the part 1 is being introduced into or removed from the space 3 in the apparatus 2 respectively, a manually-operated locking device 5 is housed, for example, of the barrel lock type, as shown in Figure 1 on the drawings. The said lock 5, which in the example shown is designed to be operated by means of a key 6 but which may of course be operated in some other appropriate way, such as, for example, as a combination lock arrangement, is connected to an actuating device 7 via an actuating spin¬ dle 8. The said spindle 8 is connected by one of its ends 8A to the locking device 5 and its other opposite end 8B, ^which is mounted in a part 9 inside the shaped part, is pre¬ ferably rigidly connected to the said actuating device 7_? which can be composed of a lever arm 7- The arm 7 is des¬ igned to be accommodated in a pocket-like chamber 10 when it is moved into a non-effective position, as shown in Figure 1. When the locking device 5 is operated, for example, by rotating the key 6, the locking device 5 actu¬ ates the spindle 8 which is rotated, ^'with the pivot arm 7_» in the direction of the arrow 11, from the rest position into a position preferably pointing upwards, as shown in Figures 2 and 4. When the arm 7 is pivoted up it co-acts with the interior 4A of the cover 4. The cover which is normally held in a pivoted-down position with the aid of a spring enclosed in the part.1, for example, is locked in the said pivoted down position by means of a locking device which is not shown on the drawings, which is released auto¬ matically when the shaped part is introduced into the space 3, by the action of a lock-releasing device 12 arranged on the part 1. A hollow space 13 which is located inside the space 3 in "the vicinity of the recording and p_).ay-back heads of the apparatus respectively, is designed to accommodate the said cover 4.

When the shaped part 1 is introduced into the space 3 in the apparatus 1 and the cover 4 is actuated by the actu¬ ating device 7 and the key 6 is removed from the locking device 5_? the cover 4 form^'s a blocking part 4 which is des¬ igned to co-act with an abutment edge shoulder 14 which is located at the transition between the hollow space 13 and the accommodating space 3- The said wider section formed by the cover 4 thus prevents the shaped part 1 from being removed from the space 3 and replaced by a full tape cass¬ ette for unauthorised use of the apparatus 2.

When the locking device 5 is operated the arm 7 is pivoted down into the rest position in the chamber 10, and the cover is thereby pivoted down under the effect of spring force and locked on the shaped part 1, after which it is possible to remove the shaped part from the space 3. Accord¬ ingly, controlled use of the apparatus 2 can take place when the shaped part 1 has been removed from the apparatus 2. The invention is not limited to the embodiment which is described above and shown on the drawings merely by way of example, but its details may be modified within the_. framework of the following Patent Claims. For example, if there is no cover on the shaped part, the actuating device can be designed to co-act with the hollow chamber.
