Description of the invention (1) 1. The technical field to which the invention belongs (please read the notes on the back before filling out this page) The present invention relates to a motor, especially to a vibration source that is used as a vibration alarm For example, a small electric motor using a calling function of a mobile communication device (for example, a mobile phone) or a somatosensory function of an entertainment device such as a game. —Observation ,, — 丄 卜 ΛΙι —, prior art As a technology in this field, there are Japanese Unexamined Patent Publication No. 1 1-136901 or Japanese Unexamined Patent Publication No. 2001-37 147. The small electric motors described in these publications are those which can be easily assembled in a communication device such as a mobile phone. A weight is fixed to the output shaft, and a terminal is fixed to the cylindrical motor case via a bracket. The terminal is formed by a leaf spring, and when the motor is to be installed on the circuit board, it is not necessary to use soldering, which can improve the efficiency of the assembly operation of the machine. However, the conventional motor described above has the following problems. That is, when the motor is intended to be mounted on a circuit board provided in the machine, the terminals are in a state where they enter the motor casing. Therefore, it is difficult to reduce the number of mobile phones, etc., due to the existence of terminals located at such positions. Disadvantages of the thickness of the machine. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The present invention was created by the creators to solve the above-mentioned problems. The purpose of the invention is to provide a machine that can promote the formation of installation objects while suppressing the installation height. Thin motor. 3. Content of the invention The electric motor of the present invention belongs to an electric paper with a substantially cylindrical shape. The size of the paper applies to the Chinese National Standard (CNS) A4 specification (210X297 mm) -5- 200301036 A7 B7 5. Description of the invention (2) (Please read the precautions on the back before filling this page.) The front end of the motor body of the chassis protrudes from the output shaft ', and the base end of a pair of terminals that supply predetermined power from the outside is' motor fixed to the motor body. A grounding portion 'is provided at the free end of each terminal having elasticity, and the interval between the grounding portions arranged at left and right positions across the central axis of the motor case is made larger than the diameter of the motor case. Printed on this motor by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the result of using a flexible terminal 'when the motor is intended to be installed on a mobile phone, etc.' can avoid the need for welding, and can improve the efficiency of machine assembly . The grounding portions of the pair of terminals are arranged across the center axis of the casing, and the interval between the grounding portions is made larger than the diameter of the casing, thereby improving the stability of the motor support when the motor is mounted. In addition, it is possible to increase the amount of elastic deformation (stroke amount) of the terminal when mounting the motor while avoiding the influence of the outer shape of the casing as much as possible. With this, the terminal is able to make full use of the elastic force required by the machine to push to the electrical contact, making the electrical connection reliable. In addition, as described above, the interval between the grounding portions is considered to give a sufficient stroke to the terminal, and the influence of the motor case is avoided as much as possible during the elastic deformation. Therefore, when the motor is installed, the terminal can be elastically deformed. The height dimension of the rear motor is as close as possible to the external dimensions of the casing. As a result, a motor with a small mounting height can be realized, which contributes to a reduction in thickness of a mobile phone or the like. Further, each terminal has a base end portion fixed to the motor case body, and an elastic portion extending from the base end portion, and a ground portion is provided at the free end, and the elastic portion is preferably disposed on one side of the motor case. In this way, as a result of the elastic portion being positioned on one side of the motor case, it is not necessary to touch the elastic portion to the motor case, and the elastic portion can be sufficiently elastically deformed. Therefore, it is possible to realize the size of the electric paper with a small installation height, which is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) 6-200301036 A7 B7 V. Description of the invention (3) Motive to promote the thinning of the machine side. The elastic portion is preferably provided with a first portion 'extending along the axis of the output shaft and a second portion extending rearward from the front end of the first portion via the bent portion. Thereby, an appropriate elastic force can be generated in the elastic portion. The base end portion extends in a vertical direction to the output shaft and bulges toward one side of the motor housing; the elastic portion preferably extends approximately U-shaped from the base end portion along the axis of the output shaft. When the terminal has an elastic portion that extends approximately U-shaped along the axis of the output shaft, the mounting height of the motor tends to increase. Therefore, the elastic portion can be set aside from the motor case and has a larger size. effect. It is also preferable to eccentrically fix the weight on the output shaft. With this configuration, a vibration motor can be constructed. Especially in a vibration motor, the support stability of the motor is very important. It is also preferable to cover the motor case with a rubber holder. Motor When vibration is applied by a weight, unnecessary vibration sound does not occur from the housing of a machine (such as a mobile phone). The motor of the present invention is highly versatile and can be applied to various vibration alarms. For example, as examples of vibration alarms, there are game devices such as mobile phones, pagers, and PDAs that carry information terminal devices or controllers of entertainment devices. Fourth, the following embodiments, the preferred embodiment of the electric motor of the present invention will be described in detail with reference to the drawings. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm). ------: --- I (Please Read the precautions on the back before filling out this page) Order printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, Consumer Cooperatives 200301036 A7 _B7 V.

A bent portion 13 a is formed on the free end side of the third portion 13. At the top, a gold-plated grounding portion 14 is bulged and formed on the surface. Such a grounding portion 14 is capable of ensuring electrical connection with a predetermined electrical contact 7 a of the circuit board 7. Such an elastic portion is extended from the expansion portion 19 in a cantilever-supported state, and the elastic portion 30 can be positioned on one side of the motor case 2. Each terminal 8 is housed in the rear end of the motor case 2 in a slit 17a (see FIG. 3) integrally formed in the leg portion 17 of the bracket 5, and the third portion 1 is exposed from the slit 17a 3. As a result, the entire terminal 8 which is easily damaged during the processing operation is not exposed, and a portion required for electrical bonding can be easily seen, thereby improving the workability of assembling to the machine. Printed by the Consumers' Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs. Furthermore, the ground portion 14 of the terminal 8 is close to the rear end of the motor case 2. As a result, the motor 1 on the circuit board 7 can be well-balanced. Furthermore, the terminal 8 formed by bending can be used to form the terminal with a simple structure and at a low cost. As a result, the manufacturing cost can be reduced. In addition, as shown in FIG. 4, the grounding portions 14 are arranged in a bilaterally symmetrical position across the central axis P of the motor case 2, and an expansion portion 30 is used at the terminal 8 to space the grounding portions 14 and 14 apart. L Dimensions of straight paper larger than the motor case 2 are applicable to Chinese National Standard (CNS) A4 specifications (210X297 mm) ~~~ 200301036 A7 B7 V. Description of the invention (7) (Please read the precautions on the back before filling in this Page) diameter R. As a result, when the motor 1 is mounted on the circuit board 7, the support stability of the motor 1 can be improved. In particular, in a vibration motor having a weight 6, the support stability of the motor 1 is extremely important. In addition, as a result of making the interval L between the ground portions 14 and 14 larger than the diameter R of the motor case 2, the shape of the motor case 2 is avoided as much as possible, and the elastic deformation amount (stroke amount) of the elastic portion 30 when the motor is mounted can be increased. ). With this, when the terminal 8 is pressed against the electrical contact 7a of a device such as a mobile phone, sufficient elastic force can be generated in the elastic portion of the terminal 8, and the electrical connection to the electrical contact 7a can be established. In addition, as described above, the interval L between the ground portions 14 and 14 is considered to avoid the influence of the motor case 2 as much as possible during the elastic deformation under the condition that the elastic portion 30 of the terminal 8 gives a sufficient stroke, so that When mounting the motor, the mounting height dimension Η (see FIG. 1) of the motor 1 after the elastic deformation of the elastic portion 30 is as close as possible to the outer diameter dimension R of the motor case 2. As a result, the motor 1 having a small mounting height size can be realized, and as a result, the thickness of the mobile phone, which is an example of a mounting object, can be reduced. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, as a result of placing the elastic portion 30 on one side of the motor case and making the space between the arranged elastic portions 30 and 30 larger than the diameter of the motor case 2, the elasticity It is not necessary for the portion 30 to contact the motor case 2 to sufficiently elastically deform the elastic portion 30. In particular, the electric motor 1 using the terminal 8 having the elastic portion 30 extending approximately U-shaped along the axis of the output shaft 3 is effective because the mounting height dimension tends to increase. The motor case 2 of the motor body A is covered with a rubber holder 16 as shown in Figs. 7 to 11. As a result, the paper size of the electric motor 1 conforms to the Chinese National Standard (CNS) A4 specification (210X297 mm) 〇200301036 A7 B7 V.

For example, the motor 40 shown in FIG. 12 has another terminal 41. This terminal 41 is formed by bending processing of a thin elastic plate cut into a predetermined shape. The terminal 41 includes a base end portion 42 fixed to the motor body A, and an elastic portion 43 having an elastic force approximately orthogonal to the output shaft 3 while extending from the base end portion 42. Each of the elastic portions 43 on both sides of the motor case 2 has a first portion 44 extending along the axis of the rotation shaft 3. In addition, the elastic portion 43 is a second portion 45 having a bent portion B in which a front end of the first portion 44 is folded in a U or V shape approximately parallel to the first portion 44. The second portion 45 is approximately the same length as the first portion 44. Further, the third portion 46 protruding outward from the rear end of the second portion 45 projects further rearward than the rear end 47 of the motor body A. A bent portion 46a is formed at the free end portion of the third portion 46, and a top portion of the bent portion 46a is formed to bulge a ground portion 49 having a gold-plated surface.
