Abstract

PURPOSE:To make the assembling easy, by assembling a numeric wheel and a pinion, while arranging oppositely a frame incorporated numeric wheel shaft and pinion shaft and a slide print plate for readout having holes to fit said shafts ls thereinto. CONSTITUTION:A frame 10 is formed while incorporated with legs 13 for both ends, numeric wheel shafts 11, and pinion shafts 12. A print plate 40 is provided with holes for the numeric wheels 11 at the center of each digit sliding part and holes for pinion shafts 12 to fit in intermediately. The numeric wheels 20 and the pinions 30 are inserted respectively to the shafts 11 and pins 12 at every one another positioning inversely upside down, the print plate 40 is inserted. Thus, the assembly can be simplified, the number of components can be decreased and the cost can be lowered.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a readout counter with parallel numeric axles, and in particular, the numeric axle and pinion shaft are integrally formed in a frame, and the sliding printed board connected to the readout is provided with the A hole is provided for the shaft end of each shaft to be inserted, and the sliding printed board is fixed to the legs extending from the frame, thereby providing a compact read-out counter with low parts cost and assembly cost. It is something.

The so-called read-out counter with number wheels arranged horizontally in half rows is well known, but conventionally, metal pins corresponding to the number of digits are caulked to a metal frame, and the number wheels are placed in the metal bin.
The pinions were combined to form a readout counter with number wheels arranged side by side.

However, the above-mentioned conventional readout counter has high parts and assembly costs, and the sliding part must be made large so that there may be a misalignment between the center of the number wheel and the center of the sliding part of the printed board. However, there were disadvantages such as requiring a large number of precious metal ovals in the sliding part and high cost.

The present invention has been made in order to solve the above-mentioned drawbacks of the prior art, and aims to provide a compact read-out counter with low parts cost and assembly cost.

FIG. 1 is a schematic configuration diagram for explaining one embodiment of a readout counter according to the present invention, in which 10 is a frame, 11 is a numerical axle, 12 is a pinion shaft, and 13 is a 7
The leg extended from the frame 10, beauty is the number wheel, 21 is the sliding contact that rotates integrally with the number wheel, :30? 1 pinion, 40 is a printed board, frame 10 and number wheel II that make up the lead-out counter! 1l111
and the pinion shaft 12 are integrally molded, and the frame 10
A pair of legs 13 extend from the axial direction. Also,
A plurality of holes are drilled in the center of the sliding part corresponding to each digit on one printed board 40 for readout, into which the shaft end of the number axle 11 is inserted, and furthermore, the distance between these holes, that is, the number wheel A hole into which the shaft end of the pinion shaft is inserted is provided at a distance of 1/2 of the distance between the number wheel and the number wheel. Therefore, sliding contact 2
Insert the number wheel and pinion adders marked 1 into the number axle 11 and pinion shaft 12, respectively, then insert each shaft end into a predetermined hole on the printed board 40, and attach the printed board 40 to the frame 10. If it is fixed to the extended legs 13, it is possible to construct a G-5 door counter with numbered wheels arranged side by side as shown in the figure.

Therefore, according to the present invention, (I) Since the numerical axle and the pinion shaft are integrated with the frame, there is no need for assembling costs for integrating them.

(2) Since the shaft end is supported by a pleated plate, the shaft support strength is greater than in the case of cantilever support, and it is easier to obtain alignment of the shaft end, and it also prevents the shaft from bending due to aging etc. It is also strong against

(3) Since the number axle is placed in the center of the sliding part on the printing plate, concentricity between the sliding part and the contact points can be obtained, and the precious metal pattern on the sliding part can be kept to a minimum, reducing costs. can do.

There are advantages such as

FIG. 2 is a schematic diagram showing the main parts of another embodiment of the present invention. In this embodiment, the height of the shaft end of each shaft is made stepwise as shown in the figure. The Puri sheet board is inserted from a high point.

Therefore, according to this embodiment, it is only necessary to repeat the operation of inserting one shaft end into each hole on the printed board, so it is possible to insert many shafts into the holes in the printed board at once. There's no need to worry about it.

FIG. 3 is a schematic configuration diagram of main parts for explaining another embodiment of the present invention. In this embodiment, the printed board 40 is a double-sided printed board, with one side having a sliding part and the other side having a sliding part. To,
It is equipped with an electrical component blade such as a line converter for transmitting electrical signals made up of sliding contacts and a printed board using fewer transmission lines.

Therefore, according to this embodiment, (1) Since signal conversion can be performed using one printed board, the counter main body can be made compact and compact.

(2) Expanding the area of a printed board by converting lines, or FPC of a first printed board that does not have enough area
There is no need for B conversion, and therefore printed root cutting becomes cheaper.

There are advantages such as

As is clear from the above description, according to the present invention, it is possible to provide a compact lead-out counter with low parts cost and assembly cost.
