  • An example of the first biasing means 234 is a spring member such as a compression spring or a torsion spring.

  • the second thermal head 242 is arranged above the second platen roller 251 and inclined downward.
  • the distal end part of the thermal paper 202 which is rolled and contained in the paper receptacle 213, passes through the nip between the second thermal head 242 and the second platen roller 251 and is fed toward the first thermal head 221.

  • An output gear 263 is mounted on the shaft 262 of the motor 261.
  • the rotation of the shaft 262 of the motor 261 (hence, the rotation of the output gear 263) is transmitted via a drive-force transmitting mechanism 264 to the first platen roller 231 and the second platen roller 251.
  • the drive-force transmitting mechanism 264 includes a reduction gear 265, a drive gear 266, the above-mentioned second platen gear 253, a pair of idler gears 267 and 268, and the above-mentioned first platen gear 241.

  • One idler gear 267 is arranged in the cover 212, and the other idler gear 268 is arranged in the printer main unit 211.
  • the idler gears 267 and 268 mesh with each other as long as the cover 212 remains closed. When the cover 212 is opened, the idler gears 267 and 268 are disengaged from each other.
  • One idler gears 267 meshes with the first platen gear 241 at all times.
  • the other gear 268 meshes with the second platen gear 253 at all times.
  • a first paper sensor 271 is arranged upstream with respect to the second thermal head 242, in the direction of feeding the thermal paper 202, in order to detect the thermal paper 202.
  • the first paper sensor 271 is electrically connected to the controller 272.
  • the controller 272 is an example of a control unit that uses a microprocessor or the like.
  • the sensing unit 271a of the first paper sensor 271 may contact the thermal paper 202 from below. In this case, the first paper sensor 271 detects the thermal paper 202. When the first paper sensor 271 detects the thermal paper 202, it outputs a signal indicating that the thermal paper 202 has been detected. The signal is supplied to the controller 272.
  • a second paper sensor 273 is arranged between the first thermal head 221 and the second thermal head 242.
  • the second paper sensor 273 is a reflection-type sensor that can optically detect the distal end of the thermal paper 202 and comprises a light-emitting element and a light-receiving element.
  • the second paper sensor 273 can detect timing marks 274 (see FIG. 3 ) that are printed on the thermal paper 202.
  • the second paper sensor 273 detects the distal end of the thermal paper 202, it generates a signal indicating that the distal end has been detected. This signal is supplied to the controller 272.
  • the timing marks 274 are marks that can be optically read.
  • An example of a timing mark 274 is a black mark (e.g., black dot) that indicates the position where the thermal paper 202 should be cut.
  • the thermal paper 202 is a double-sided thermal paper and has two thermosensible layers 204 and 205 on the obverse and reverse sides, respectively. Therefore, the first thermal head 221 can print the timing marks 274 on the first thermosensible layer 204, or the second thermal head 242 can print the marks 274 on the second thermosensible layer 205. To enable the second paper sensor 273 to detect the timing marks 274, however, the second thermal head 242 prints the timing marks 274. This is because the second thermal head 242 is arranged upstream with respect to the sensor 273 in the direction of feeding the thermal paper 202.
  • the thermal paper 202 may be replaced by a single-sided thermal paper having only one thermosensible layer. If this is the case, the timing marks 274 are printed on the reverse side of the thermal paper (i.e., the side on which no thermosensible layers are provided). That is, the second paper sensor 273 of this embodiment can detect the timing marks 274 printed on the double-sided thermal paper 202 and the timing marks printed on a single-sided thermal paper.
  • the controller 272 To control the position where to cut the thermal paper 202, by using the timing marks 274, the controller 272 outputs pulses to the motor 261 when the timing marks 274, in number that corresponds to the distance for which the paper 202 has been fed. On the bases of the number of pulses received, the motor 261 is driven by a prescribed angle. That part of the thermal paper 202, which is to be cut, therefore reaches the cutter mechanism 233.
  • the cover 212 When the cover 212 is opened to replenish the thermal paper 202, the first platen roller 231 moves away from the first thermal head 221. At the same time, the second thermal head 242 moves away from the second platen roller 251. Further, the one idler gear 267 is disengaged from the other idler gear 268. The top of the printer main unit 211 is therefore opened. As a result, the first thermal head 221 and the second platen roller 251 are fully exposed to the outside.
  • the first biasing means 234 keeps pushing the first thermal head 221 toward the first platen roller 231
  • the second biasing means 254 keeps pushing the second thermal head 243 toward the second platen roller 251.
  • the idler gears 267 and 268 come into mesh with each other.
  • the thermal paper 202 is set in the paper receptacle 213, and the distal end of the paper 202 is led to the second thermal head 242. Then, the first paper sensor 271 detects the thermal paper 202, and the controller 272 outputs pulses. These pulses drive the motor 261 by the prescribed angle in the direction of arrow R shown in FIG. 1 . The second platen roller 251 is thereby rotated in the direction of arrow R2. The thermal paper 202 is therefore fed toward the first thermal head 221.
  • the rotation of the shaft 262 of the motor 261 is transmitted via the drive-force transmitting mechanism 264 to the first platen roller 231 and the second platen roller 251.
  • the first platen roller 231 and the second platen roller 251 therefore rotate in the direction of arrow R1 and the direction of arrow R2, respectively.
  • the second paper sensor 273 detects the thermal paper 202.
  • the controller 272 When the second paper sensor 273 detects the distal end of the thermal paper 202, the controller 272 outputs pulses. The pulses drive the motor 261 further, by the prescribed angle. Then, the thermal paper 202 is stopped at a preset printing position, with its distal end clamped between the first thermal head 221 and the first platen roller 231.
  • the controller 272 When the controller 272 outputs a signal to the motor 261, instructing that data be printed, the motor 261 rotates the first platen roller 231 and the second platen roller 251 in the directions of arrows R1 and R2, respectively. At this time, the first thermal head 221 prints data on the first thermosensible layer 204 of the thermal paper 202. At the same time, the second thermal head 242 can print data on the second thermosensible layer 205 of the thermal paper 202. If necessary, the second thermal head 242 can print, on the desired parts of the second thermosensible layer 205, timing marks 274 that indicate the position where the paper 202 should be cut.
  • the thermal paper 202 is fed toward the cutter mechanism 233. While the thermal paper 202 is being fed so, the second paper sensor 273 detects the timing marks 274. Thereafter, the paper 202 is further fed in accordance with the number of pulses output from controller 272, until that part of the thermal paper 202, at which the paper 202 is to be cut, reaches the cutter mechanism 233. Then, the cutter mechanism 233 operates, cutting the thermal paper 202.
  • the thermal printer 201 has a paper-reversing function of driving the motor 261 in the reverse direction in order to move the distal end of the thermal paper 202 cut by the cutter mechanism 233, back to a position near the first thermal head 221. Since the paper-reversing function can return the distal end of the paper 202 to a position near the first thermal head 221, the paper 202 can be prevented from having an unprintable region, i.e., blank region. Thus, the thermal paper 202 will not be wasted.
  • the thermal paper 202 can be cut, without using timing marks 274. If no timing marks 274 are used, the pulses output from the controller 272 drive the motor 261 by the prescribed angle, thereby feeding the paper 202 until the part of the paper 202, which is to be cut, reaches the cutter mechanism 233. Then, the cutter mechanism 233 operates, cutting the thermal paper 202.
  • Timing marks may be already printed on the reverse side of a single-sided thermal paper (i.e., the side on which no thermosensible layers are provided).
  • the position at which to cut the paper can be designated if the second paper sensor 273 detects the timing marks printed on the single-sided thermal paper.
  • the thermal printer 201 according to this embodiment can use not only double-sided thermal papers, but also single-sided thermal papers.
  • the components of the invention such as the first and second thermal heads, first and second platen rollers, cutter mechanism, drive-force transmitting mechanism, first paper sensor and second paper sensor, can of course be modified as needed.
  • the marks printed on the thermal paper are not limited to timing marks. Any other optically readable marks may be printed, instead.
