A sectional view taken along line A and FIG. 3 are development views of the contact sheet portion. In FIG. 3, reference numeral 11 denotes an insulating and elastic sheet such as polyester (hereinafter referred to as a contact sheet) on which contacts are adhered, which is formed in a rectangular shape having an aspect ratio of about 1: 2. In the left front, for example, the extension
12 are integrally formed. Further, on one surface of the contact sheet 11, in this figure, on the surface of the contact sheet 11, for example, contacts 13, 14, 15 and lead lines 16a, 16b, 16c made of a mixture of silver and copper are formed by a method such as printing. It is adhered and formed. In this case, the contact 13 is formed in the right half region of the contact sheet 11 radially outward from the center of the region to the middle thereof and radially in the circumferential direction, and further, the center side end thereof. The parts are connected to each other. Further, the contacts 14 are formed radially outside the contact 13 in the radial direction from the center to the outside, and further, the outer ends thereof are connected to each other. Further, as shown in detail in FIG. 4 (shown by the solid line), the contact 1
The widths of 3, 14 are, when viewed in the circumferential direction, half of the repeated forming period T of these contacts, and
The positions (phase of the array) in the circumferential direction of the contact 13 and the contact 14 are shifted by 1/4 of the cycle T. Further, the contact 15 is formed in a circular shape so as to be common to the contacts 13 and 14 in the left half region of the contact sheet 11. Lead lines (wiring patterns) 16a, 16b, 16c are formed integrally with the contacts 13, 14, 15 to the extension portion 12 and extend from the contact portions 13, 14, 15 to the extension portion 12, respectively.
In the connection terminal 17. As shown in FIGS. 1 and 3, the contact sheet 11 is bent so that the contact points 13 and 14 and the contact point 15 face each other with the chain line 18 as the center. In this case, a sheet-shaped spacer 21 is inserted and arranged between the contacts 13 and 14 and the contact 15. As shown in FIG. 5, the spacer 21 is made of a sheet of insulating film or the like, and the entire size thereof is equal to the left half of the contact sheet 11, and the portion corresponding to the extension 12 is formed in a slightly shorter shape. There is. And, as shown by the broken line in FIG.
Eight fan-shaped through-holes 22 are formed at positions opposed to 4. Further, as shown in FIGS. 1 and 2, a decorative sheet 31 is provided on the surface of the contact sheet 11 opposite to the surface on which the contacts 13 and 14 are formed. The decorative sheet 31 is formed in the same shape as the spacer 21 by an insulating film or the like. The guide emboss 3 is provided on the surface of the decorative sheet 31 at positions corresponding to the inner and outer circumferences of the contacts 13 and 14.
2, 33 are integrally formed in an annular shape, and a space between the emboss 32 and the emboss 33 is a pressing operation portion 34. To assemble this encoder, the spacer 21 may be stuck between the contact sheets 11, and the decorative sheet 31 may be further stuck. When the encoder is mounted on the target device, the connection terminal 17 is soldered, or
By being inserted into the connector jack, it is connected to the other party, for example, a printed circuit board. According to this structure, the contact 13 and the contact 15 make the first
Switch 41 is formed, and the contact 14 and the contact 15 form a second switch 42.
When the operation unit 34 is pressed, 1, 42 are turned on or off depending on the pressed position. When the operating portion 34 is pressed with a finger or the like and traced in the clockwise direction or the counterclockwise direction, the first and second switches 41 and 42 are alternately turned on and off.
At 17, the switch output is available. For example, the outputs of the switches 41 and 42 when the angle section of one cycle T as shown in FIG. 4 is traced with a finger are as shown in FIG. That is, the switch 42 is turned on in the section from the angular position a to the angular position c and turned off in the other section, and the switch 41 is turned on in the section from the angular position b to the angular position d and turned off in the other section. become. Then, at this time, since the contact 13 and the contact 14 are formed with a phase difference of T / 4 arrangement, the first and second switches 41 and 41 from the connection terminal 17 are
As shown in FIG. 6, the switch output of 42 has a phase difference of π / 2, and the phase of the output is changed by tracing the finger clockwise and counterclockwise. The relationship between lead and lag is reversed. As described above, it is possible to obtain an encoder output at the connection terminal 17 by tracing the operation unit 34 while pressing it with a finger. Thus, according to the present invention, the encoder output can be obtained. In this case, in particular, according to the present invention, the contact sheet 11 is provided with the contacts 13 to 15 and the decorative sheet 31.
Since the contact sheet 11 and the spacer 21 are simply laminated, the structure is extremely simple and the assembly is easy. Further, it can be made small and thin without the need for a dial, and has a good spacer factor when incorporated in an electronic device. Further, the number of parts is small, and since it can be configured only by a simple sheet-shaped member, it is low cost. Moreover, the connection terminal 17 can be formed simultaneously with the contacts 13 to 15, and it is not necessary to separately prepare the terminals. Further, since the switches 41 and 42 are closely closed, they have excellent environmental resistance. Furthermore, when tracing the operating portion 34 while pushing the operating portion 34 with a finger, the embossments 32 and 33 serve as guides, so that the operability is also excellent. 7 to 11 show an embodiment in which the present invention is applied to a linear encoder, and these drawings correspond to FIGS. 1 to 5, respectively. Further, the portions corresponding to those in the above-described embodiment are designated by the same reference numerals and the description thereof will be omitted. And in the encoder of this example, the contacts 13 to 15,
The embosses 32, 33 and the operating portion 34 are formed in a linear shape. Therefore, the operation unit 34 can obtain an encoder output in which the relationship between the lead and the delay of the phase is reversed when the finger traces in the left direction and the right direction in the figure. In the above description, instead of providing the embosses 32, 33, the operation portion 34 may be recessed to serve as a guide. Further, although the contact sheet 11 is bent from the folding line in the above-mentioned example, the contact sheet may be separated into the left side portion 11A and the right side portion 11B, and they may be overlapped with each other via the spacer. However, in that case, as shown in FIG. 12, the lead lines 16a and 16b from the contacts 13 and 14 are formed on the sheet on the right side.
