A transmission unit mounted on the machine base of an office automation machine and covered with a cover and controlled to turn a document feeding control roller through a first driven gear set and/or a thermal paper letting-off control roller through a second driven gear set, including motor, a drive gear turned by the motor, a gear transmission mechanism which includes a first planet gear, a second planet gear, and a sector gear respectively turned by the drive gear to turn the first driven gear set and/or the second driven gear set, and a memory transmission setting mechanism which includes an electromagnetic valve, and a reciprocating rod reciprocated by the electromagnetic valve and having a front notch at a front end thereof, the front notch of the reciprocating rod being forced into engagement with the gear shaft of the first planet gear to disengage the first planet gear from the first driven gear set when the fax machine is set at the memory transmission mode.

Single-motor type transmission unit of an office machine

A transmission unit mounted on the machine base of an office automation machine and covered with a cover and controlled to turn a first roller and a second roller, including a gear transmission mechanism, a first roller having a driven gear set at one end, and a second roller having a driven gear set at one end, wherein the gear transmission mechanism includes a motor, a rounded seat raised from the machine base, a drive gear mounted on the rounded seat and coupled to the motor, a first annular gear holder revolvably mounted around the rounded seat and having an upright gear shaft, a second annular gear holder revolvably mounted around the rounded seat and having two upright gear shafts, an auxiliary gear mounted on the machine base, a first planet gear revolvably mounted around the gear shaft of the first annular gear holder and driven by the drive gear to turn the driven gear set of the first roller, a second planet gear revolvably mounted around one upright gear shaft of the second annular gear holder and meshed between the drive gear and the auxiliary gear and driven by the drive gear to turn the driven gear set of the second roller, and a sector gear meshed with the drive gear and forced to turn the driven gear set of the second roller reversely through a fixed angle after the copy or incoming mode.

Transmission unit of an office machine

A transmission unit mounted on the machine base of an office automation machine and covered with a cover and controlled to turn a first roller and a second roller, including a gear transmission mechanism, a first roller having a driven gear set at one end, and a second roller having a driven gear set at one end, wherein the gear transmission mechanism includes a motor, a rounded seat raised from the machine base, a drive gear mounted on the rounded seat and coupled to the motor, a first annular gear holder and a second annular gear holder revolvably mounted around the rounded seat and having a respective upright gear shaft, a crank turned about a pivot on the machine base and having an upright gear shaft at the free end, a first planet gear revolvably mounted around the gear shaft of the first annular gear holder and driven by the drive gear to turn the driven gear set of the first roller, a second planet gear revolvably mounted around the upright gear shaft of the crank and forced by the drive gear to turn the driven gear set of the second roller in letting of the thermal paper, and a sector gear mounted around the upright gear shaft of the second annular gear holder and forced by the drive gear to turn the driven gear set of the second roller reversely through a fixed angle after each operation of the copy or incoming mode.

Motor-driven transmission unit of a fax machine

A transmission unit mounted on the machine base of an office automation machine and covered with a cover and controlled to turn a first roller and a second roller, including a gear transmission mechanism, a first roller transmission mechanism driven and a second roller transmission mechanism respectively driven by the gear transmission mechanism to turn the rollers, wherein the gear transmission mechanism includes a motor, a rounded seat raised from the machine base, a drive gear mounted on the rounded seat and coupled to the motor, an annular gear holder revolvably mounted around the rounded seat and having an upright gear shaft, an upright axle raised from the machine base adjacent to the rounded seat, a crank having a pivot hole at one end coupled to the upright axle and a gear shaft at an opposite end, a first planet gear revolvably mounted around the gear shaft of the crank and driven by the drive gear to turn the first roller transmission mechanism, a second planet gear revolvably mounted around the gear shaft of the annular gear holder and driven by the drive gear to turn the second roller transmission mechanism; the cover has an arched slot, which receives the gear shaft of the annular gear holder to guide the movement of the second planet gear along the teeth of the drive gear within a fixed angle.
