Description

Transaction machine

The present invention relates to a transaction machine, and more particularly to a transaction machine in which an upper cover is lowered relative to a base to close the cover.

With the development of a multi-functional technology, more and more business machines have functions such as fax, scanning, photocopying and printing. This not only enables the transaction machine to have multiple document processing capabilities, but also makes the volume more compact. The assembly process is simple, and only need to connect the telephone line, the network route and the power cord to be used with the computer, thus making the transaction machine more and more popular.

A conventional transaction machine includes a scanner (Scanner) and an automatic paper feeding device (ADF). When the internal printer needs to change ink or eliminate the abnormal paper jam, the scanner and the automatic paper feeding device must be turned over, but since the scanner and the automatic paper feeding device have a considerable weight, the conventional machine is set. The linkage mechanism cannot smoothly support the scanner and the automatic paper feeding device, which not only causes the scanner and the automatic paper feeding device to fall, but also causes injury to the user.

3 to FIG. 6 are schematic diagrams showing the operation flow of the closing cover of the transaction machine of FIG. As shown in FIG. 3, in general, when the upper cover 220 is in an open state with respect to the base 210, the upper cover 220 is pivoted with one side connected to the base 210, and the other side not connected to the base 210 is relatively far away. Base 210. At this time, the link set 230 is not in contact with the damper 240. Then, referring to FIG. 3, FIG. 4 and FIG. 5, when the upper cover 220 is closed relative to the base 210, the upper cover 220 may be connected to the side of the base 210 by manual, program control or electric means. The other side, which is not connected to the base 210, is rotated in a clockwise direction to be relatively close to the base 210. Affected by the rotation of the upper cover 220, the link set 230 is also moved, wherein the first link 232 is moved by the upper cover 220 while also slightly rotating clockwise, and at the same time the second link 234 is subjected to the first Influenced by the movement of the link 232, the third end 234a of the second link 234 rotates clockwise with the fourth end 234b as an axis, and the link set 230 in turn contacts the buffer block 244 of the damper 240. The second end 232b of the first link 232 or the third end 234a of the second link 234 is in contact with the buffer block 244 of the damper 240. The link set 230 actually contacts the buffer block 244 of the damper 240. The part is determined according to the actual configuration relationship of the link set 230 and the damper 240 according to the design requirements.

Since the fixed rails 212 are disposed not in such a manner that the longitudinal direction D and the normal direction are parallel or perpendicular to each other, the longitudinal direction D of the fixed rails 212 is substantially parallel to the second of the first links 232 of the link set 230. The connection between the end 232b and the third end 234a of the second link 234 is in the direction of the track in which the closing procedure may move, so that during the closing process, the link set 230 contacts the damper 240, and the weight of the upper cover 220 The linkage set 230 is in turn continuously pressed against the bumper block 244 of the damper 240. The force received by the bumper block 244 of the damper 240 is transmitted to the first spring 242, and the first spring 242 is forced to be deformed by force, and the buffer block 244 is moved along the length direction D of the fixed rail 212. It should be noted that while the link set 230 begins to press on the buffer block 244 of the damper 240, the elastic restoring force of the first spring 242 provides a reaction force smaller than the downward force of the upper cover 220, so that the upper cover 220 is a relative base. The seat 210 slowly descends until the upper cover 220 is closed relative to the base 210, as shown in FIG.

When the upper cover 220 is opened relative to the base 210, the operation between the link set 230 and the damper 240 is reversed in FIGS. 3 to 6, and will not be described here.

In the transaction machine 200 of the present embodiment, a damper 240 having a buffer block 244 and a first spring 242 is used to provide the upper cover 220 on the opposite base, compared to the conventional transaction machine using only a combination of the sliding shaft and the bracket. When a 210 is closed, a feedback force buffers the speed at which the upper cover 220 is closed relative to the base 210, thereby preventing the weight of the upper cover 220 from being too heavy to hit the base 210 or injuring the maintenance personnel. In addition, the components used in the damper 240 are easy to obtain or manufacture, so the material cost is not expensive, and the overall cost of the transaction machine 200 can still be effectively controlled.
