The present invention relates to a data recorder equipped with a recording card selection mechanism.

Various configurations of data recorders with selection mechanisms are known.

These include a housing for receiving a stack of discrete recording cards and a keyboard having correspondingly labeled keys for selecting the cards whose activation is desired. The record card may contain miscellaneous information in alphabetical order for later reference. A well-known data recorder is relatively flat when closed and is opened by a plurality of keys that are manually actuated to open the desired record card at the desired time, thereby freeing the information on that card. It is configured as seen in . A data recorder configured in this manner also allows the cover covering the recording card to be moved to the closed position, and upon closing the cover, the raised recording card can be automatically returned to its original position. Equipped with a close key. Furthermore, there is a drawer for receiving a recording card fastened by a bolt and under the action of a thrust spring, and a drawer is unlocked and a recording card selected by a selection key is released by pushing out the unlocked drawer by the thrust spring. Data recorders are also well known which include a housing with a device for.

These known data recorders are constructed as footed devices and are placed on a support.

The housing of the data recorder also has a surface that serves as a telephone holder, if the housing is provided with a drawer that allows the selected recording card to be moved out of the housing. However, all of these data recorders typically have a keyboard located in the front portion of the recorder that includes a plurality of selection keys arranged in rows.

Furthermore, known data recorders are known to be relatively large in size. It is further provided that the cards are horizontally stacked in a drawer selected by pressing a selection key and disposed in an opening in the front wall of the housing and are moved horizontally within the housing to a closed position and in relation to the initial stress. stored in a housing, the latch being moved out of the housing to an open position where it can be locked, and having a latch at one end movably secured within the housing and having a shirtcle that is initially stressed and mated to a notch in the drawer; Devices for selecting one of a plurality of cards are well known. The rod further includes a rod rotatably fixed within the housing, one end of which is provided with a manually operable key located on the outside of the housing, and the other end of which is provided with a manually operable key located on the outside of the housing. When you press the key on the green side of the shoulder to remove the key, all the cards above the card associated with the key are prevented from moving with the drawer, and the selected card and the card below it are a key bar having a shoulder cooperating with a force bar arranged in a row in the recess so as to be moved with the drawer;
is provided for each card. In the case of this known selection mechanism, a plurality of card cams corresponding to the number of cards are pivotally supported by the drawer and are arranged by a mounting member at the end of the key lever opposite to the key, and the cams When the corresponding key is pressed down, the selected card and the cards below it can be moved to the green matching position, and the mounting section to cooperate with the card can be moved above the selected card at the same time. It is configured to engage with the concave portions of all cards present in the card to prevent their movement. This known selection mechanism consists of a plurality of card cams corresponding to the number of cards, which are pivotably supported in a drawer and brought into the operating position by means of a key lever mounting member, and are mounted in a manner that cooperates with the cards. It has a very complicated structure because the member is configured to simultaneously engage the recesses of all the cards above the selected card to prevent their movement.

The object of the present invention is to provide a data recorder which is reliable in operation and allows a completely satisfactory separation of automatically selected recording cards even in the case of careless operation at great technical outlays. The goal is to provide the following. According to the invention, this object is achieved in that the selection keys of the rocking lever include plate-like square or rectangular parts fixed to their ends, and the selection keys arranged one behind the other in a row are Contains three selection keys, the selection key facing the card restraining pin on the rear side of the swing lever protrudes above the two adjacent swing levers on the right side, and the front selection key on the left side. The central selection key protrudes above two adjacent swing levers and is connected to the swing levers on both sides adjacent to the key so as to protrude left and right. The card restraining pin of each rocking lever is formed at its end with a vertically oriented rod that engages the opening or recess of the recording card from below when the rocking lever is actuated. a generally U-shaped portion formed at the end of the rocking levers having legs leading to the selection keys, each rocking lever having a card deterrent pin at the end for guiding the rocking lever; It has a vertical slot-like closure in which a cam formed on the inner wall surface of the housing cover is engaged and guided, and a mechanism for unlocking the drawer is connected to the cover of the housing and extends in the longitudinal direction of the swing lever. includes a U-shaped shirtcle whose web, perpendicular to A type as previously indicated, comprising a locking cam on its bottom face facing the drawer, cooperating with a counter-cam formed in the drawer such that the locking cam is released from the counter-cam as it is pulled out. solved by a data recorder.

A data recorder constructed according to the invention has several components: a housing, a drawer, a swinging lever formed with a selection key and a guard restraining pin, and a swinging lever that is actuated directly by the swinging lever during operation. A record card selection mechanism is provided that can be manufactured very inexpensively due to the oscillating shirtcle 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 construction and arrangement of the selection key with respect to the rocking lever, the rocking lever is arranged very tightly and can therefore 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 slope of the housing. Completely reliable operation of the data recorder is achieved by actuating the swing lever without any additional mechanical devices to be provided with the swing to control the unlocking mechanism of the drawer, which can be actuated directly by the swing lever. Also guaranteed by the lever. Since the swinging motion of each swinging lever is directly transmitted to the swinging shirtcle,
Due in part to direct actuation of the drawer lock release mechanism, the drawer is unlocked as soon as the card restraint pin engages the closure of a recording card remaining in the housing, allowing access to the selected card and any underlying cards. It is moved out of the housing along with the stack. By forming this card deterrent according to the invention, in a data recorder,
The separation of the card stack into a lower part, which is reliably transported with the drawer, and an upper part, which is sufficiently ensured against movement, is achieved automatically and in accordance with the selected card's presence even in case of inadvertent manipulation. A card deterrent device is provided.

Only by additionally arranging the cam-like extension on the U-shaped card restraint part, the unselected and restrained card can be easily removed when the recording card becomes misshapen or slightly bent after long-term use. Even if the adhesion between the drawn card and the remaining card is strong when the drawer is pulled out, it cannot be torn. Furthermore, the special formation of the card restraint part avoids premature lifting of restrained recording cards, so that loose cards can also be partially torn when moved out of the card stack together with selected cards. He can't. Furthermore, this advantageous effect is achieved without additional and further technical equipment, so that a low-cost production of such a data recorder is possible. 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 large in size and has a slot-like recess in the rear end area of the drawer that corresponds to the bend with the card-retaining pin at the end of the swing lever, so that it can be easily inserted during insertion of the drawer. This is achieved by fitting the bent portion into the slot-like recess.

In this way, the drawer can take on a large size, so
The entire support surface of the drawer is utilized for recording cards and large cards can be used. The invention will be described in detail below with reference to an example embodiment and the accompanying drawings, in which: FIG.
