The card has a very complicated structure because it is configured to simultaneously engage with the recesses of all the cards above the selected card to prevent their movement.

The object of the invention is to provide a completely satisfactory recording card of a selected type without extensive technical outlay, with a very small size, reliable operation and minimal area arrangement of the selection keys. The object of the present invention is to provide a data recorder that enables separation.

According to the present invention, this problem is solved by the selection keys of the rocking lever including a plate-shaped square or rectangular portion fixed to the end thereof, and the selection keys arranged in a row one after another. Contains three selection keys, the selection key facing the card restraining pin at the rear end of the swing lever protrudes above the two swing levers adjacent to the right side, and the front selection key is adjacent to the left side. The width corresponds to the width of the two swinging levers that protrude from the two swinging levers connected to each other so that the center selection key projects left and right onto the swinging levers on both sides adjacent to the key. a selection key having a card-retaining pin on each rocking lever formed at its end with a vertically upwardly oriented rond that engages an aperture or recess in the recording card from below when actuating the rocking lever; a housing cover at the end of each swing lever having a card-retaining pin for guiding the swing lever; a vertical slot-shaped opening in which a cam formed on the inner wall surface of the housing is engaged and guided, and a mechanism for unlocking the drawer is connected to the cover of the housing and is perpendicular to the longitudinal direction of the swing lever. , the web of which includes a U-shaped shackle located on the upper surface of the swinging lever and subject to actuation of the swinging lever, each shackle member allowing the drawer to be moved out when the shackle is lifted by operating a selection key. Data of the type previously indicated, comprising a locking cam on its bottom face facing the drawer, cooperating with a counter-cam formed on the drawer such that the locking cam is released from the counter-cam as it is pulled out; Solved by recorder.

A data recorder constructed according to the invention allows several components to be used, namely the housing, the drawer, the swing lever formed with the selection key and the card-retaining pin, and which can be actuated directly by the swing lever during operation. A recording card selection mechanism is provided that can be manufactured very inexpensively for a swing shackle drawer unlocking mechanism.

Due to the small number of components, assembly is simple and can be performed even by inexperienced personnel.

The reduced number of components is particularly advantageous when making necessary repairs.

Due to the special structure and arrangement of the selection keys with respect to the rocking levers, the rocking levers are so densely arranged that they can be accommodated in a very small part of the housing.

The placement of the card-retaining pin at the end of the swing lever into a recess formed in the bottom plate of the housing allows for a shallow construction of the data recorder.

Even when the selection key is actuated incorrectly, there is no problem since the end of the rocking lever with the card-retaining pin is individually cam-guided and no tilting or movement of the end area of the rocking lever is possible. Exact selection is not possible.

No additional device is required to support the rocking lever in its initial position by means of a spring-actuated device.

The end of the swing lever with the card-retaining pin is supported on the bottom plate of the housing.

A completely reliable operation of the data recorder is achieved by the rocking mechanism for controlling the unlocking mechanism of the drawer, which can be actuated directly by the rocking lever without any additional mechanical devices to be provided. Also guaranteed by the lever.

Since the rocking motion of each rocking lever is directly transmitted to the rocking shackle, there is also direct actuation of the drawer lock release mechanism so that the card restraint pin engages the opening of the recording card remaining in the housing and simultaneously The drawer is unlocked and moved out of the housing along with the selected card and the underlying stack of cards.

The housing of the data recorder is also manufactured inexpensively, since a box-shaped drawer is no longer necessary.

The drawer simply consists of a plate-like member without side walls and rear wall.

The side wall is constituted by a limiting wall formed on the inner surface of the housing cover.

Furthermore, the housing is very small in size, and it is provided with a slot-like recess in the rear end area of the drawer corresponding to the bend with the card-retaining pin at the end of the swing lever, so that the bend during insertion of the drawer This is achieved by fitting the part into the slot-like recess.

Thus, the drawer can take on a large size so that the entire support surface of the drawer is available for recording cards and large cards can be used.
